The AirTAC GFR60020ALNWTK AirTAC Filter Regulator NPT3/4 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60020ALNWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 configuration has 3/4 in NPT ports, a 5 um filter element (code W), an automatic drain, and the low-pressure regulator type (code L). A check valve is fitted (code K) and a mounting bracket is included; no gauge is fitted (code N). The bowl is aluminium alloy, which is standard at size 600, and the unit takes up to 1.0 MPa (145 psi) inlet pressure over a temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus options for drain type, filter grade, gauge and thread (PT is the standard; G and NPT are order options). Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet details for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtered, low-pressure regulated air feeding rinse and blow-off nozzles on a bottling line. The 5 um element keeps nozzles clear, the automatic drain clears collected condensate, and the check valve blocks backflow into the supply.
Steady low-pressure air across air knives drying cans on a conveyor. The size-600 aluminium-alloy bowl and 3/4 in NPT ports suit a main supply drop, while the automatic drain handles moisture without daily attention.
Conditioned supply air to a powder-coating booth, where water and fine particulate in the air line would spoil the finish. The low-pressure regulator type matches booth supply pressures, and the check valve protects the setting from reverse flow.
Size 600 is the largest step in the GFR range (200/300/400/600), paired here with 3/4 in NPT ports - step up or down a size to match the pipe and the flow your line needs. This code carries the 5 um element (W) instead of the 40 um standard, the automatic drain instead of manual or differential-pressure, and the low-pressure regulator type (L); the exact regulated range for the low-pressure type is not published, so confirm it with us. A gauge can be added at order time (embedded square, or external round with MPa, psi or bar scale) - this unit ships without one. Thread is NPT here; PT is the catalogue standard and G is also available. Bracket included.
Because rated flow is published only as curves, not a single number, send us your application conditions and we will confirm sizing from the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm sizing for this exact model from the datasheet on request.
L is the low-pressure regulator type - the exact regulated range for this type is not published, so confirm it with us for your setpoint. N means no gauge is fitted. A gauge can be specified at order time: an embedded square gauge or an external round gauge with MPa, psi or bar scale.
